My first suggestion with any modem problems is try a plain old terminal
program such as minicom and try manually issuing the commands. Some PPP
dialers also offer a 'terminal window' or something for this purpose.

not quiet, verbose on, echo on, answer on zero rings, CD pin follows
carrier signal, return to command mode if DTR pin is lowered (typically
when app closes or hangup button pressed), Fax Class zero.
If the modem has no idea what fax is, it may baulk at the +FCLASS
commands.

factory settings, echo off*, verbose on, answer on 7th ring, no idea, no
idea, no idea - modem specific, can't remember.
The echo off is possibly a problem, especially if the application is
expecting the command to be echoed (besides responded to).
In your terminal package or terminal window you should be able to issue
some command and have them respond with OK, except for dial commands which
usually give CONNECT, NO DIALTONE, BUSY, RING etc. If you get ERR or ERROR
one of the components of the command went wrong.
Modems strings start with AT, there are no double letter commands but some
are prefixed with & % or \. If they are prefixed with \ you have to
sometimes put \\ in scripts. Some commands are suffixed with a digit eg
"V0" and "V1" are two settings for the verbose command. There are internal
registers on modems indicated by Snn and these are set with Snnn=nnn
format. Whitespace between commands is optional.
